REGISTERING MECHANISM.

To all whom it may concern Be it known that I, ()smn F. l onsnnuo, a citizen of the United States, residing at Yonkers, in the county of \Yestchester and State of New York, have invented a certain new and useful Improvement in Registering Mechanisms, of which the following is a full, clear, concise, and exact description.

This invention relates to registering mechanisms, and more particularly to manually-set electrically-controlled apparatus for counting telephone conversations.

The principal object of this invention is to provide an improved register of the above type, wherein the electromagnetic register and circuit-controlling system may operate with equal eiiiciency, whether or not the call is registered, and wherein a manually set mechanism causes the registration in a single positive movement.

To the above end a manually operated cam-like structure places the register train actuator in operative relation to the train, and closes a signaling circuit, after which the manual control is transferred to the electromagnetic system. The electromagnet, whose movement is controlled by the direc tion of current through its winding, actuates the release, the movement of which is the same whether or not the call is to be registered, holds the circuit closed, and likewise controls the registering actuator which is operated in a single positive movement.

.The above and other objects of this invention will be fully set forth in the following description and claims, and will be more readily understood by reference to the accompanying drawings in which Figure 1 is a side elevation of the entire mechanism assembled and in normal posi-' tion, the inclosing housing being broken away on the line 1-1 of Fig. 2; Fig. 2 is an end elevation, the inclosing housing being broken away on the line 22 of Fig. 1: Fig. 3 is a detail view of a part of the electromagnetic controlling structure; Fig. 4 is a perspective view of the cam structure and some of its cooperating elements broken away from the rest of the structure to more clearly illustrate the construction; Fig. 5 is a side elevation of a part of the setting and controlling mechanisms in their relative positions when the push button is fully depressed; and Figs. 6 and 7 are "skeleton views of a part of the setting and control- Specification of Letters Patent.

ling mechanism showing their relative position upon being released for a successful and unsuccessful call. respectively.

The entire mechanism is supported upon the base plate 5 and is protected from molestation and injury by an inclosing case (i. A. bracket 7, secured to the base plate 3, carries the frame members 8 an 9 between and to which most of the various moving parts are pivot-ally mounted.

-tmanually operable member or cam is actuated by the manipulation of a. push button 10 which extends through the inclosing case, (3. The push button 10 engages a roller 11 carried by a lever 12. Lever 12 is pivoted between the :l'rame members 8 and 9 at 13 and carries at its free end a pawl 14. It will be readily apparent that the depression of the push button 10 causes the lever 12 to rotate about its pivot 13 and consequently the advancement of the pawl 14:. The pawl 11 is niovably secured to the lever 12 by means of a pivot pin 15 and is held to its work, hereinafter set fortli, by a spring 16. sprinq 20, secured atone end to the frame member 8 and at the other to the lever 12, serves to normally hold the free end of the lever 12 and the pawl 14 carried thereby in a retracted position, as shown in Fig. 1. A stop 21 confines this upward movement to the desired limits.

The pawl l-l. is adapted to engage one of the teeth of a three-tooth ratchet :25, which is pivoted between the frame members 8 and 9 on a. shaft 26. Firmly secured to the ratchet 25 by pins 27 is a three-point cam 28 which is likewise rotatable about the shaft 26 upon a depression of the pawl 11.

The pins 27 are inclosed by rubber rollers 30, and besides acting as connecting links between the ratchet 25 and the cam 28, serve in connection with the release, to be hereinafter described, to limit the movements of the cam and register actuator. Upon the surface of the cam 28 a roller 35 carried by the spring-tensioned lever 36 bears. The lever 36 is pivoted between the members 8 and 9 at 37, and is under the tension of a spring 38. The end of the lever 36, opposite the roller 35, -arries an actuating pawl 40 which is pivoted thereto at 41. A'ratchet 42, secured to a units registering wheel 43', is in a position to be engaged and rotated by the actuating pawl 40. Additional Wheels 44, adapted to be rotatably desired.

moved by the units wheel 43 at the proper.

intervals, serve to register the calls in units, tens, hundreds and thousands. A spring member 45, secured at one end to a projection 46 on the lever 36 and at the other end to a projection 47 on the pawl 40', tends to lower the operating end of the pawl 10 into engaging relation to the ratchet 42, but such movement is controlled by electromagnetic means to be hereinafter described.

The manipulation of the push button serves to control circuit contacts by means of which a signal is produced to notify the central otlice operator that a connection is A laterally projecting lug 50 on the frame member 9 carries a pair of contact springs 51 and 52 which are insulated from each other and the frame by suitable insulating strips 53. Contact spring 51 is in such a position that its free end is adapted I to be engaged by the insulating rollers 30, thereby being depressed, upon the rotation of the ratchet 25, until it makes contact with its companion spring 52. This closes the circuit for the central office signal.

Electromagnetic means are employed to effect the release, control the registration, and secure reliable operationby holding the circuit contacts closed. The base plate 5 is equipped with a bracket 55 which serves as a support and, heel iron for the magnet coils 56. A movable armature 57 is pivoted therebetween on pivot screws 58 and is adapted to be moved in either direction depending upon the polarity of current traversing the coils 56. Likewise mounted upon and movable about the pivots 58 are two independent levers 60 and 61. These levers are provided with pins 62 which bear against the armature 57, and through which they receive the motion thereof. The levers 60 and 61 are also provided with tensioning springs 63 which return them and the armature 57 to normal. position upon the deenergization-of the coils 56. Armature 57 is provided with an arm 65 which carries an insulating roller 66. This roller 66 normally rests within and near the apex of a V-shaped portion of a release 67. Release 67 is pivoted at 68 to a bearing member 69 which is secured to the frame member 9 and is rotated about its pivot 68 by the engagement of the roller 66 and the sides of its V- shaped portion upon each movement of the armature 57. The placing of the roller 66 within the a ex of the V-shaped portion of the release 67 moves said release in the same direction irrespective of the direction of movement of the armature, and provides for an equally efficient movement in either direction, since in neither case is the roller compelled to ride. over the V-shaped portion.

A laterally extending end of the release 67, when the mechanism is in normal positlon, as shown 1n Fig. '1, is in a position to engage one of the rollers 30 on the pins 27. When the push button 10 has been completely depressed as shown in Fig. 5, the cam 28 has been rotated in the direction of the arrows until the roller 35, carried by the lever 36, has just passed beyond the apex of one of the cam points and is'on the downwardly sloping side thereof. In this position a stop 76 engages the underside of the lever 12, preventing its further depression by the push button 10 and the control of the mechanism is transferred from the manual to the electromagnetic system. The pressure of spring 38 exerted upon the cam 28 through the lever 36 and the roller 35 tends to rotate the cam 28 until the roller 35 reaches the lowest portion between two consecutive, cam points. However, the engage ment of extension 75 of release 67 with one of the rollers 30 prevents such advancement. The energization of the coils 56, however, moves the roller 66 to depress the release 67 and its laterally extending end portion 75 until engagement between one of the rollers 30 and the end 75 is broken. The tension exerted by spring 38 may thereupon rotate the cam 28 in the direction of the arrows until the normal position is reached, as shown in Fig. 1. The lever 36, as the roller 35 moves down the surface of one of the cam points advances the actuating pawl 40 upon the ratchet 42, and registration is controlled by register-controlling means actuated from the armature 57.

The armature-actuated lever 60 carries an upwardly extending arm 80 which is provided with a laterally extending portion 81. The laterally extending portion 81 normally rests beyond a chamfered portion of a tail 82 of the actuating pawl 40 and rests upon the main body portion of the tail 82 when the pawl 40 is withdrawn after the manipulation of the button 10. When the armature 57 is moved in a direction to register, it not only actuates the release 67 but also moves the lever 60, about the axis58, which carries its arm 80 and the portion 81 to the position shown in Fig. 6. The tail 82 of the pawl 40, being freed from the influence of the extension,8 1 of the arm 80, allows the spring 45 to lower the forward end of the pawl 40 to engage the teeth of the ratchet 42 which is rotated one step'. The position of the pawl 40 before and after advancement is shown bythe full and dotted. lines, respectively, of Fig. 6. If the. armature 57is held tilted in the registering direction, further manipulation of the push button 10 does not cause false registrations since a projecting lug 83 on the arm 80 engages a projection 84 on the pawl 14, moving the free end of the pawl l iout of engaging relation to the ratchet 25,

without registration, the armature would be tilted in the opposite direction, the release 67 would be moved as before, and the pawl 40 would be advanced by spring 38. The lever 60, however, would not be rotated and consequently the projection 81 of the arm 80 would remain in engagement with the tail 82. This engagement between the tail 82 and the projection 81 prevents the spring 45 from lowering the forward end of and carries an insulating button 86. Whenthe' armature 57 rotates the release 67 about its pivot, the button 86 is moved into engagement with spring 51, holding said spring in engagement with its companion spring as long as the armature is tilted in either direction. A tensioning spring 87 secured to the frame and the extension 85 serves to return the release to normal position upon the denergization of the coils 56.
